Web2PDF Online is a free service that will convert HTML to PDF for your websites so your visitors can quickly save information on your site to a PDF file. It also keeps track of all of the PDF conversion activities on your site.

It only takes 3 steps to set it up on your site or blog. 1) set the conversion options (page setup, etc) and test it. 2) create the Javascript for your site and 3) copy and paste the Javascript onto your site to create the widget.

The site offers support and it is really easy to use.

This could be a good option if you would like people to be able to save parts of your blog or website as a PDF file, including having students do it as an archive of material for their notes.
